The Samsung Indie printer lets you plug your smartphone in and use it to play music on stereo speakers while you print, while the Samsung Wave is a toilet-shaped printer that doesn’t have speakers but does let you dock your smartphone and print content that’s stored on it. Finally, Samsung is showing off the Samsung One & One, which it says is “a mono laser printer” that “allows the user to print using two colors by designating one additional color from cyan, magenta, or yellow to complement the standard black.”
